Display problem

When I run my program it asks for the food and drink total but after I enter the amount and hit "enter" the program just ends. I just want a little help as to what I'm doing wrong please.

Code:

#include <iostream>

using namespace std;

int main()
{
    double FDT;
    double tax;
    double tip;
    double GT;
    
    cout << "Enter the food and drink total:";
    cin >> FDT;
    
    tax = FDT*0.07;
    
    tip = FDT*0.18;
    
    GT = FDT + tax + tip;
    
    cout << "\n************************";
    
    cout << "\n*";
    
    cout << "\n*      Bill Calculation  ";
    
    cout << "\n*";
    
    cout << "\n* Food and drink total:" << FDT;
    
    cout <<"\n* Tax at 7%:" << tax;
    
    cout <<"\n* Tip at 18%:" << tip;
    
    cout <<"\n* Grand total:" << GT;
    
    return 0;
    
}

Thanks a lot for your help, greatly appreciated.
